Mikroelektronika MIKROE-2035 ULN2003A Stepper Motor Driver, 30V, 500mA, mikroBUS Click Board

Technical description of the product (MIKROE-2035):

MIKROE-2035 ULN2003A is a high-current Darlington transistor array with a power supply up to 30V. Stepper 3 click is designed to drive unipolar stepper motors, with a supply voltage applied to the common wire. The current flows through the common wire and the motor coil, via the activated current sink driver, to the ground. This Click board uses the ULN2003A, a high voltage and current Darlington transistors array IC, as the sink driver. This IC is an ideal solution for this purpose, as it has seven high power Darlington output stages, activated by TTL/CMOS logic level signals, applied to the control pins. This allows driving unipolar stepper motors with up to 30V and 500mA per coil. Type: Stepper. Applications: It can be used for precise and reliable unipolar stepper motor control applications. Besides driving unipolar stepper motor as the primary function, this Click board can also be used for driving relays, brushed DC motors, etc. On-board modules: ULN2003A, a high voltage and current Darlington transistors array IC, from Texas Instruments. Key Features: High power Darlington sink drivers with up to 500mA per channel, clamping diode for the kickback voltage protection, can be used for other applications such as driving relay coils or brushed DC motors, etc. Interface: GPIO. Input Voltage: 5V. Compatibility: mikroBUS. Click board size: M (42.9 x 25.4 mm).
